Baltimore's health commissioner saw an immediate impact.
Dr. Joshua Sharfstein, Commissioner of Health in Baltimore said, " the number of calls for poison control dropped dramatically. over 50 percent."

Scharfstein said, "826 under six is where the greatest risk for a serious side effect is."

Linda Suydam with the Consumer Healthcare Products Association said, "these products are safe for children over the age of two.
